ELM 5-635 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-635 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.635" (16.13mm) length. This component is constructed from black PVC material and accommodates 3MM 2-lead LED configurations. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when inventory constraints, lead time requirements, or specific application geometries necessitate alternative standoff heights while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 5-635 is determined by the following critical parameters:

Mandatory Matching Parameters:

• LED Type: T1
• Mounting Orientation: Vertical
• Material: Black PVC
• Lead Configuration: 2LD (2-Lead)
• Color: Black
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Variable Parameter (Allows Substitution):

• Length: 0.635" (16.13mm) — Substitute parts may vary in standoff height within the ELM series product line

The ELM 2-665 qualifies as a parametric equivalent because it maintains all mandatory matching parameters while providing an alternative length specification of 0.665" (16.89mm). This length variation accommodates applications requiring different vertical spacing while preserving the core T1 LED standoff functionality.

Engineering Selection Recommendations

Primary Selection (ELM 5-635): Select the ELM 5-635 when the application requires a 0.635" (16.13mm) standoff height. This part is Active status with full ROHS3 compliance and unlimited moisture sensitivity rating, suitable for standard production applications.

Substitute Selection (ELM 2-665): The ELM 2-665 serves as a substitute when the 0.635" height specification cannot be met due to inventory availability or lead time constraints. The 0.665" (16.89mm) length provides a 0.030" (0.76mm) increase in standoff height. This substitute maintains identical compliance certifications (ROHS3, EAR99) and MSL rating, ensuring equivalent environmental and regulatory performance.

Both parts are manufactured by Bivar Inc. and carry Active product status, confirming ongoing production support and supply chain viability.

Frequently Asked Questions (FAQ)

Q: Can the ELM 2-665 be used in place of the ELM 5-635 without circuit board redesign?

A: The ELM 2-665 introduces a 0.030" (0.76mm) increase in standoff height. Substitution feasibility depends on the application's vertical clearance tolerance. If the circuit board layout accommodates this height variation, substitution is electrically and mechanically valid. If vertical spacing is constrained, board redesign may be required.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, EAR99 ECCN classification, and MSL rating of 1 (Unlimited). They are equivalent from a regulatory and environmental standpoint.

Q: What is the primary difference between ELM 5-635 and ELM 2-665?

A: The primary difference is standoff length. The ELM 5-635 provides 0.635" (16.13mm) height, while the ELM 2-665 provides 0.665" (16.89mm) height. All other parameters—LED type, material, lead configuration, color, and compliance ratings—are identical.

Q: Can these parts be mixed in the same assembly?

A: Mixing parts with different standoff heights in a single assembly is not recommended unless the circuit board design explicitly accommodates variable LED heights. Consistent standoff height ensures uniform LED plane alignment and optical performance.

Q: What packaging format is used for these parts?

A: Both parts are supplied in Bag packaging format, suitable for component handling and storage in production environments.
